Repair of Isolated Subscapularis Tears With Concurrent Biceps Tenodesis Using a Single Anchor Results in Satisfactory Clinical Outcomes: Minimum 2-Year Follow-Up

Purpose: To investigate the clinical outcomes of patients treated with isolated subscapularis tear repair and biceps tenodesis using a single anchor. Methods: Patients diagnosed with subscapularis tear and who underwent arthroscopic surgery by a single surgeon between February 2017 and January 2022 were evaluated retrospectively. Inclusion criteria were patients who underwent repair of isolated subscapularis tear along with tenodesis for long head of the biceps tendon pathologies such as SLAP lesion, instability, partial tear, or tenosynovitis, with a minimum follow-up of 24 months. Assessment included active and passive range of motion, single-assessment numeric evaluation (SANE), visual analog scale (VAS), Constant-Murley score (CMS), and specific subscapularis and biceps tests. Improvements were analyzed using minimum clinically important difference (MCID) values. Results: A total of 20 patients were included. The mean age was 48.5 ± 7 years, and the follow-up period was 43.1 ± 12.7 months. Significant improvements were observed at the final follow-up in active forward flexion, active abduction, active internal rotation, as well as VAS, SANE, and CMS (P < .001). The MCID analysis showed that 100% of patients met the MCID for CMS, 90% for SANE, and 100% for VAS. Conclusions: In the presence of an isolated subscapularis tear associated with long head of the biceps tendon pathologies, favorable clinical outcomes could be achieved by performing both tear repair and biceps tenodesis with a double-loaded single anchor. Most patients (>90%) achieved the MCID for the CMS, SANE, and VAS, indicating significant clinical improvement and satisfactory patient outcomes. Level of Evidence: Level IV, case series.
